Hot-Dip Galvanizing a ni

Galvanized steel pipe hi a chung lamah zinc venna layer hmanga khuh steel pipe chi khat a ni. Zinc coating hian physical barrier angin a thawk a, sacrificial anode angin a thawk bawk a, chu chu coating chu a hrual a nih pawhin a chhehvela zinc chu a corrode hmasa ber a, chu chuan a hnuaia steel chu oxidation laka a humhim thei a ni. Hei hian galvanized pipe te chu hmun hnim emaw, hnim hring emaw-ah nasa takin a chhe thei lo.
Galvanizing hman dan tlangpui pahnih a awm a:

• Electro-galvanizing hmanga siam a ni– Zinc layer te tak te, a chunglam a hrual, adhesion tha tak, mahse corrosion resistance a hniam zawk.
• A lumna-dip galvanizing (HDG) hmanga siam a ni.– Steel pipe tihfai chu molten zinc-ah 450–500℃-ah thun a ni a, chu chuan zinc-iron alloy layer chu steel-ah metallurgically-in a inzawm a, a chung lam layer chu zinc thianghlim a siam a ni. Coating thickness hi 35 μm atanga 650 μm thleng a ni thei a, electro-galvanizing nena khaikhin chuan corrosion resistance leh service life tha zawk a pe thei a ni.

Zinc layer thick, uniform leh strongly bonded a nih avangin hot-dip galvanized steel pipe hi tui supply, gas distribution, petrochemical facilities, construction, guardrails, leh outdoor structures-ah te hman a ni nasa hle a, hei hian economical leh long-term protection solution a pe a ni.

• ASTM A123 a ni– Thir leh Steel thil siama Zinc (Hot-Dip Galvanized) Coatings
• ASTM A53 (Galvanized hmanga siam theih) .– Galvanized steel pipe seamless leh welded a ni
• BS 1387 a ni– Tui, gas leh steam siamna tur hot-dip galvanized pipe
• GB/T 3091 a ni– Welded galvanized steel pipe hmanga low-pressure fluid phurh chhuahna tur

• Barrier venhimna a ni– Zinc coating hian steel chu tui leh oxygen atanga a thliar hrang thin.
• Cathodic humhalhna a ni– Zinc hian a corrode duh zawk a, exposed steel chu scratch emaw edge emaw ah a venghim.
• Alloy Layer hmanga inzawmna siam a ni– Zinc-iron alloy layer hian adhesion tha tak a pe a, peeling emaw flaking emaw a do thei bawk.

• Rawngbawlna Hun rei zawk– Boruak boruak pangngaiah chuan galvanized pipe hi kum 30–50 chhung a daih thei a; industrial emaw coastal environment-ah chuan kum 15–20 chhung humhalh hi a awm tlangpui.
• Coverage kimchang tak neih a ni– Pipe pumpui chungah venhimna inang tlang a pe a, weld, corner, leh hard-to-reach area te pawh a huam tel.
• Cost-A hlawkthlak hle– One-time galvanizing hian kum sawm tam tak chhung venhimna a pe a, service life chhungin maintenance leh repainting senso a tihtlem phah a ni.
• Durability sang tak a nei– Metallurgical zinc-iron alloy layer hi handling, shipping, leh installation-ah abrasion leh mechanical impact lakah a do thei hle.
• Eco-Ṭhian ṭha tak a ni– Zinc hi recycle theih a ni a, hot-dip galvanizing hian painting system tam tak nena khaikhin chuan environment a nghawng tlem zawk.
• Inspection awlsam tak a ni– Coating thickness leh surface quality hi awlsam takin mit hmuha enfiah emaw, thickness gauge hmanga finfiah theih a ni.

• Municipal Project hrang hrang a awm bawk: Tui pekna, gas pipeline, drainage system
• In sakna Industry a ni: Scaffolding, guardrail, structural support te a awm bawk
• Energy Sector a ni: Petrochemical, natural gas, steam sem dan
• Infrastructure & Transport lam thil a ni: Bridge guardrail, kawngpui fencing, highway structure siam te a ni
• Agriculture & Industry lam a ni: Tui pek dan tur, warehouse siamna tur, fencing siamna tur

Octal Pipe-ah hian hot-dip galvanized pipe hi QA/QC system khauh tak hnuaiah siam a ni:

• ASTM/BS/GB standard angin coating thickness testing (μm emaw g/m2) a ni
• Adhesion, uniformity, leh chi spray test te a awm bawk
• Defect-free finish a nih theih nan full dimensional leh visual inspection neih a ni
• Steel grade hrang hrang, diameter hrang hrang, leh sei zawng hrang hranga supply flexible
• Project pawm theihna tur quality documentation kimchang leh traceability

• Indawtdan: Zinc hmin (molten zinc)-ah 450–500 degree-a thun tur
• Zinc Coating a ni: 35–650 μm
• Size hrang hrang: 1⁄2′′ – 20′′ (DN15 – DN500) a ni.
• Standard hrang hrang: A rilru a hah lutuk chuan a rilru a buai em em a, a rilru a hah lutuk chuan a rilru a buai em em bawk a. BS 1387, GB/T 3091
• Dilna hrang hrang: Tui, gas, in sak, chakna, infrastructure
• Rawngbawlna Nun: Environment a zirin kum 20–50 chhung a ni
